People learn better from graphics and narration than from graphics, narration, and printed text. Redundancy can create extraneous processing because of the overload of information in the visual channel due to efforts in trying to absorb and compare the visual information to the auditory information. The extraneous processing is diminished when the captions are next to the image and very short; the spoken text is presented before the printed text; there are no graphics and verbal segments are short.
